If anyone is interested, I created a GWT test app styled with Bootstrap. The code is almost entirely written by Grok (99%). Quite amazing what AI can do !

Very cool.  Impressive it didn't cheat and actually coded it with GWT UI Binder and JSNI.

Why did it use JSNI ? it's a bit young for that

There’s also the GwtBootstrap3 library that’s open source (and has its own similar demo app). Wonder if the AI had that in its training material …

Possibly because Grok originally generated it for GWT 2.7 as I recall and I then told Grok the latest version was 2.12.2 and not all the code was re-factored.

I specifically told Grok I didn't want to use GWTBootstrap3 as I wanted the latest Bootstrap and wanted to minimise dependencies.

All those AI tools give/prefer JSNI code over JsInterop.

For example yesterday I was looking for using SVG in GWT. And Gemini told me I could for example wrap svg.js in a gwt wrapper. And explicitty told me that JSNI was a better option then JSinterop with some reasons. It showed examples of both but recommended going with JSNI.

In the past I also have seen it multiple times that Gemini and Copilot tell me to use JSNI.


(personnally I actually also find JSNI to be a better solution, but I don't use it anymore because of the promise of GWT 3 (?...?))

JSNI is probably easier than jsinterop in the bootstrap example ? no js file to create and load, no annotations, but
1) bit fiddly calling JSNI methods from js,
2) doesn't do non-native exports ?

That's actually an interesting question:  sometimes ai will hallucinate but not to the degree of invoking an unmentioned framework in my experience. It sticks to the gwt framework and as expected & provides the most common solution given the docs it has read, which implies JSNI is documented more than jsinterop
